Synology RackStation RS3618xs 12-Bay NAS Server

The Synology RS3618XS is a rackmount network storage server that lets growing businesses and creative teams keep large volumes of data safe, organized, and always available. With room for twelve SATA hard drives or solid-state drives, it provides a generous pool of space that can start small and expand as projects multiply.

Inside, a quad-core Intel Xeon D-1521 processor works alongside 8 GB of error-correcting DDR4 memory. If you add more users or heavier workloads, the memory can grow to 64 GB, so performance stays steady even when several virtual machines, surveillance feeds, or development builds run at the same time.

Four Gigabit Ethernet ports sit on the rear panel. You can join them to boost throughput for a busy design studio, or keep them separate to create failover paths that maintain access during a cable or switch outage. Two open PCIe 3.0 slots accept optional 10 GbE network cards or an NVMe SSD cache card, giving you a direct path to higher network speeds or faster IOPS when databases or video editing timelines demand it.

For companies that rely on virtualization, the server fits neatly into VMware, Windows Hyper-V, Citrix, and OpenStack environments. Snapshot technology in the Btrfs file system allows point-in-time recovery, while automatic self-healing checks guard against silent data corruption. You can set up traditional RAID levels or choose Synology Hybrid RAID, which simplifies mixed-drive configurations and makes future capacity upgrades straightforward.

Backup tools built into Synology DiskStation Manager give you granular control over Windows and Linux workstations, virtual machines, and even Microsoft 365 or Google Workspace accounts. Whether you need an on-site destination for cloud copies or a primary file server with cloud sync, the software covers both scenarios from a single, browser-based console.

When storage needs surge, attach up to two Synology expansion units and grow from twelve to thirty-six drives without shutting anything down. The chassis uses efficient cooling and power-saving features to stay quiet in the rack and keep operating costs predictable. A five-year warranty provides long-term confidence for IT managers and business owners alike.
